UQFB-200 - 200Amp Circuit Breaker

UQFB-200 - 200Amp Circuit Breaker

The Milbank UQFB-200 delivers reliable overcurrent protection for utility metering and service entrance applications. This 200 amp circuit breaker uses a bolt-on mounting style that holds the breaker firmly in place after installation, helping prevent loose connections over time. With a 240 volt rating, it supports higher-load residential systems and select light commercial setups without unnecessary complexity. The thermal magnetic trip reacts quickly to short circuits while protecting against sustained overloads during normal operation. The breaker carries a 10,000 amp interrupt rating and meets UL listing requirements commonly specified for metering and service equipment. Electricians and contractors choose the UQFB-200 when they need a straightforward breaker that performs consistently in everyday electrical systems.
